Fomes lamacnsis; and Coriolopsis Copclandii equals Fomes rosco- 

 albus. The author reports a very extensive and rich fungous flora, 

 with much still to be learned. 



In an article by Schmitz and Zeller on the effect of creosote on 

 wood-destroying fungi, published in the Journal of Industrial and 

 Engineering Chemistry, it is stated that the results of experiments 

 indicate no toxic effects of any single distilled fraction or combina- 

 tion of fractions of the coal-tar creosote below a concentration of 

 i per cent, calculated on the weight of air-dried sawdust. That is, 

 there was no visible cessation of growth of either Lenzitcs saepiaria 

 or Polyporus lucidus below a i per cent concentration. In a 

 majority of cases the toxic point, which is defined as the minimum 

 percentage of the creosote which will completely inhibit the growth 

 of the organisms, lies between 2 and 4 per cent. 



A splendid illustrated paper on " The Collybias of North Caro- 

 lina," by Coker and Beardslee, appeared in the Journal of the 

 Elisha Mitchell Scientific Society for December, 1921. Twenty- 

 two species are recognized for the state, one of them, Collybia 

 lilacina, being described as new. This species seems fairly abun- 

 dant about Chapel Hill, and Dr. Coker has illustrated it both in 

 color and in black and white. Our American C. butyracca is 

 shown to be for the most part simply a large form of C. dryophila; 

 and C. subdryophila, described by Atkinson from specimens col- 

 lected in North Carolina by Coker, is considered a synonym of 

 C. dryophila. The authors make C. strictipes Peck equivalent to 

 C. nummularia Fries and Mycena palustris (Peck) Sacc. a syn- 

 onym of C. clusilis. They also discuss the relationship of C. 

 tuberosa and C. cirrata; and include C. conigena Fries, C. hari- 

 olorum Fries, C. semkalis Fries, and C. distorta A. & S. as good 

 American species. 



Dr. B. M. Duggar writes me that my report of his paper at the 

 Toronto meeting, published on page 51 of the January number of 

 Mycologia, is not in accordance with what he meant to convey. " I
